CPSO is introduced as a new search engine for optimal sensor network design purposes. Furthermore, a Square Root Unscented Kalman Filter (SRUKF) algorithm is employed as a new data reconciliation technique to enhance the stability and accuracy of the filter. The proposed design procedure incorporates precision, cost, observability, reliability together with importance-of-variables (IVs) as a novel measure in Instrumentation Criteria (IC). To the best of our knowledge, no comprehensive approach has yet been proposed in the literature to take into account the importance of variables in the sensor network design procedure. In this paper, specific weight is assigned to each sensor, measuring a process variable in the sensor network to indicate the importance of that variable over the others to cater to the ultimate sensor network application requirements. A set of distinct scenarios has been conducted to evaluate the performance of the proposed methodology in a simulated Continuous Stirred Tank Reactor (CSTR) as a highly nonlinear process plant benchmark. The obtained results reveal the efficacy of the proposed method, leading to significant improvement in accuracy with respect to other alternative sensor network design approaches and securing the definite allocation of sensors to the most important process variables in sensor network design as a novel achievement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constriction%20coefficient%20PSO" title="constriction coefficient PSO">constriction coefficient PSO</a>, <a href="https://publications.waset.org/abstracts/search?q=importance%20of%20variable" title=" importance of variable"> importance of variable</a>, <a href="https://publications.waset.org/abstracts/search?q=MRMSE" title=" MRMSE"> MRMSE</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20network%20design" title=" sensor network design"> sensor network design</a>, <a href="https://publications.waset.org/abstracts/search?q=square%20root%20unscented%20Kalman%20filter" title=" square root unscented Kalman filter"> square root unscented Kalman filter</a> </p> <a href="https://publications.waset.org/abstracts/141781/a-sensor-placement-methodology-for-chemical-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141781.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> An Approach for Association Rules Ranking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rihab%20Idoudi">Rihab Idoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Saheb%20Ettabaa"> Karim Saheb Ettabaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Basel%20Solaiman"> Basel Solaiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamel%20Hamrouni"> Kamel Hamrouni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Medical association rules induction is used to discover useful correlations between pertinent concepts from large medical databases. Nevertheless, ARs algorithms produce huge amount of delivered rules and do not guarantee the usefulness and interestingness of the generated knowledge. To overcome this drawback, we propose an ontology based interestingness measure for ARs ranking. According to domain expert, the goal of the use of ARs is to discover implicit relationships between items of different categories such as ‘clinical features and disorders’, ‘clinical features and radiological observations’, etc. That’s to say, the itemsets which are composed of ‘similar’ items are uninteresting. Therefore, the dissimilarity between the rule’s items can be used to judge the interestingness of association rules; the more different are the items, the more interesting the rule is. In this paper, we design a distinct approach for ranking semantically interesting association rules involving the use of an ontology knowledge mining approach. The basic idea is to organize the ontology’s concepts into a hierarchical structure of conceptual clusters of targeted subjects, where each cluster encapsulates ‘similar’ concepts suggesting a specific category of the domain knowledge. The interestingness of association rules is, then, defined as the dissimilarity between corresponding clusters. That is to say, the further are the clusters of the items in the AR, the more interesting the rule is. We apply the method in our domain of interest – mammographic domain- using an existing mammographic ontology called Mammo with the goal of deriving interesting rules from past experiences, to discover implicit relationships between concepts modeling the domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=association%20rule" title="association rule">association rule</a>, <a href="https://publications.waset.org/abstracts/search?q=conceptual%20clusters" title=" conceptual clusters"> conceptual clusters</a>, <a href="https://publications.waset.org/abstracts/search?q=interestingness%20measures" title=" interestingness measures"> interestingness measures</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology%20knowledge%20mining" title=" ontology knowledge mining"> ontology knowledge mining</a>, <a href="https://publications.waset.org/abstracts/search?q=ranking" title=" ranking"> ranking</a> </p> <a href="https://publications.waset.org/abstracts/47971/an-approach-for-association-rules-ranking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47971.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Relationship Between Health Coverage and Emergency Disease Burden</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Hajjar">Karim Hajjar</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Lillo"> Luis Lillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Martinez"> Diego Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Hermosilla"> Manuel Hermosilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Risko"> Nicholas Risko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: This study examines the relationship between universal health coverage (UCH) and the burden of emergency diseases at a global level. Methods: Data on Disability-Adjusted Life Years (DALYs) from emergency conditions were extracted from the Institute for Health Metrics and Evaluation (IHME) database for the years 2015 and 2019. Data on UHC, measured using two variables, 1) coverage of essential health services and 2) proportion of population spending more than 10% of household income on out-of-pocket health care expenditure, was extracted from the World Bank Database for years preceding our outcome of interest. Linear regression was performed, analyzing the effect of the UHC variables on the DALYs of emergency diseases, controlling for other variables. Results: A total of 133 countries were included. 44.4% of the analyzed countries had coverage of essential health services index of at least 70/100, and 35.3% had at least 10% of their population spend greater than 10% of their household income on healthcare. For every point increase in the coverage of essential health services index, there was a 13-point reduction in DALYs of emergency medical diseases (95% CI -16, -11). Conversely, for every percent decrease in the population with large household expenditure on healthcare, there was a 0.48 increase in DALYs of emergency medical diseases (95% CI -5.6, 4.7). Conclusions: After adjusting for multiple variables, an increase in coverage of essential health services was significantly associated with improvement in DALYs for emergency conditions. There was, however, no association between catastrophic health expenditure and DALYs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergency%20medicine" title="emergency medicine">emergency medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=universal%20healthcare" title=" universal healthcare"> universal healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20health" title=" global health"> global health</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20economics" title=" health economics"> health economics</a> </p> <a href="https://publications.waset.org/abstracts/157299/relationship-between-health-coverage-and-emergency-disease-burden" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157299.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">64</span> Comparative Study Using WEKA for Red Blood Cells Classification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jameela%20Ali">Jameela Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20A.%20Jalab"> Hamid A.

Karim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drying is a food processing technique where simultaneous heat and mass transfer take place from surface to the center of the sample. Deformation of food materials during drying is a common physical phenomenon which affects the textural quality and taste of the dried product. Most of the plant-based food materials are porous and hygroscopic in nature that contains about 80-90% water in different cellular environments: intercellular environment and intracellular environment. Transport of this cellular water has a significant effect on material deformation during drying. However, understanding of the scale of deformation is very complex due to diverse nature and structural heterogeneity of food material. Knowledge about the effect of transport of cellular water on deformation of material during drying is crucial for increasing the energy efficiency and obtaining better quality dried foods. Therefore, the primary aim of this work is to investigate the effect of intracellular water transport on material deformation during drying. In this study, apple tissue was taken for the investigation. The experiment was carried out using 1H-NMR T2 relaxometry with a conventional dryer. The experimental results are consistent with the understanding that transport of intracellular water causes cellular shrinkage associated with the anisotropic deformation of whole apple tissue. Interestingly, it is found that the deformation of apple tissue takes place at different stages of drying rather than deforming at one time. Moreover, it is found that the penetration rate of heat energy together with the pressure gradient between intracellular and intercellular environments is the responsible force to rupture the cell membrane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20and%20mass%20transfer" title="heat and mass transfer">heat and mass transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20material" title=" food material"> food material</a>, <a href="https://publications.waset.org/abstracts/search?q=intracellular%20water" title=" intracellular water"> intracellular water</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20rupture" title=" cell rupture"> cell rupture</a>, <a href="https://publications.waset.org/abstracts/search?q=deformation" title=" deformation"> deformation</a> </p> <a href="https://publications.waset.org/abstracts/76634/effect-of-cellular-water-transport-on-deformation-of-food-material-during-drying" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76634.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> A Comparative Study for Various Techniques Using WEKA for Red Blood Cells Classification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jameela%20Ali">Jameela Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20A.%20Jalab"> Hamid A.

The result of that is innovative changing a great deal of a great deal of assumption, concepts, transactions, and high of competition between companies all over the world. The title of the thesis is one of the subjects that get large concerns in the financial and business world in the present time. That is because many competitive firms have appeared in the regional and global markets and the rapid changes that covered all fields of life. The subjects of the dissertation have a special importance in making the firm's businesses succeed in general and the industrial firms especially. Thus, the basic purpose of this study is to determine whether target costing is used in the costing application process in their customer expectation, profit margin, cost and price determination, cost reduction and management operations. In today’s intensely competitive and highly volatile business environment, consistent development of low cost and high quality products meeting the functional requirements is a key to a company's survival. Companies continuously strive to reduce the costs while still producing quality products to stay ahead in the competition. Many companies have turned to target costing to achieve this objective. The results indicate that there is a significant positive relationship (at the significance level less than 0.05) between the factors competitive advantage and management accounting techniques in the firm's sample study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=strategic%20information" title="strategic information">strategic information</a>, <a href="https://publications.waset.org/abstracts/search?q=target%20cost" title=" target cost"> target cost</a>, <a href="https://publications.waset.org/abstracts/search?q=competitive%20advantage" title=" competitive advantage"> competitive advantage</a>, <a href="https://publications.waset.org/abstracts/search?q=Iraqi%20soft%20drink%20firms" title=" Iraqi soft drink firms"> Iraqi soft drink firms</a> </p> <a href="https://publications.waset.org/abstracts/36850/the-impact-of-strategic-information-in-developing-the-target-cost-approach-to-achieve-competitive-advantage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36850.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Out of Hospital Cardiac Arrest in Kuala Lumpur: A Mixed Method Study on Incidence, Adherence to Protocol, and Issues</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Said%20Nurumal">Mohd Said Nurumal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Sheikh%20Abdul%20Karim"> Sarah Sheikh Abdul Karim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Information regarding out of hospital cardiac arrest incidence include outcome in Malaysia is limited and fragmented. This study aims to identify incidence and adherence to protocol of out of hospital cardiac arrest and also to explore the issues faced by the pre-hospital personnel in regards managing cardiac arrest victim in Kuala Lumpur, Malaysia. A mixed method approach combining the qualitative and quantitative study design was used. The 285 pre-hospital care data sheet of out of hospital cardiac arrest during the year of 2011 were examined by using checklists for identify the incidence and adherence to protocol. Nine semi-structured interviews and two focus group discussions were performed. For the incidence based on the overall out of hospital cardiac arrest cases that occurred in 2011 (n=285), the survival rates were 16.8%. For adherence to protocol, only 89 (41.8%) of the cases adhered to the given protocol and 124 did not adhere to such protocol. The qualitative information provided insight about the issues related to out of hospital cardiac arrest in every aspect. All the relevant qualitative data were merged into few categories relating issues that could affect the management of out of hospital cardiac arrest performed by pre-hospital care team. One of the essential elements in the out of hospital cardiac arrest handling by pre-hospital care is to ensure increase of survival rates and excellent outcomes by adhering to given protocols based on international standard benchmarks. Measures are needed to strengthen the quick activation of the pre-hospital care service, prompt bystander cardiopulmonary resuscitation, early defibrillation and timely advanced cardiac life support and also to tackle all the issues highlighted in qualitative results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-hospital%20care" title="pre-hospital care">pre-hospital care</a>, <a href="https://publications.waset.org/abstracts/search?q=out%20of%20hospital%20cardiac%20arrest" title=" out of hospital cardiac arrest"> out of hospital cardiac arrest</a>, <a href="https://publications.waset.org/abstracts/search?q=incidence" title=" incidence"> incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=protocol" title=" protocol"> protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20method%20research" title=" mixed method research"> mixed method research</a> </p> <a href="https://publications.waset.org/abstracts/12852/out-of-hospital-cardiac-arrest-in-kuala-lumpur-a-mixed-method-study-on-incidence-adherence-to-protocol-and-issues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12852.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">414</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Comparative Study Between Oral and Intralesional Injection of Beta Blocker in the Treatment of Infantile Capillary Hemangioma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadeen%20Eltoukhy">Nadeen Eltoukhy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20S.%20Sheta"> Sahar S.

Methods: The study enrolled 40 infants diagnosed with infantile capillary hemangiomas. Patients were divided into 2 groups: Group A (Non-invasive group) included 20 infants who received oral propranolol hydrochloride starting at a dose of 1 mg/kg/day BID, then increased to a max of 2 mg/kg/day BID gradually over 2 weeks for 3 months. Group B (Invasive group) included 20 infants who received intralesional propranolol injection at a dose of 1 mg/mL; the volume of the injected drug depended on the size of the lesion (0.2 mL injected per cm of lesion diameter), with a maximum volume of 1 mL for a lesion of 5 cm diameter under complete aseptic conditions in the operating theater. Results: At three months after initiating treatment, the circumferential size of the hemangioma showed a statistically significant decrease in both groups; in Group A from 3.66±2.89 cm to 1.56±1.26 cm with p-value <0.05 and in Group B from 2.99±2.73 cm to 1.32±1.18 cm with p-value <0.05. There is no statistically significant comparative difference between the two groups (p-value = 0.538 = insignificant). Regarding the complications of oral propranolol, one patient (5%) had bradycardia, and one patient (5%) had diarrhea. In the injection group, 20 patients (100%) had local edema, and one patient (5%) had a local infection. Conclusions: Both oral non-invasive and intralesional invasive propranolol are safely used to successfully treat and decrease the size of infantile hemangioma while showing no statistically comparative difference between both treatment techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hemangioma" title="hemangioma">hemangioma</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20beta%20blocker" title=" oral beta blocker"> oral beta blocker</a>, <a href="https://publications.waset.org/abstracts/search?q=intralesional%20beta%20blocker" title=" intralesional beta blocker"> intralesional beta blocker</a>, <a href="https://publications.waset.org/abstracts/search?q=infants" title=" infants"> infants</a> </p> <a href="https://publications.waset.org/abstracts/182961/comparative-study-between-oral-and-intralesional-injection-of-beta-blocker-in-the-treatment-of-infantile-capillary-hemangioma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182961.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">52</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Combined Effect of Moving and Open Boundary Conditions in the Simulation of Inland Inundation Due to Far Field Tsunami</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Ashaque%20Meah">M.

To compute the effect of far field tsunami and extent of inland inundation due to far field tsunami along the coastal belts of west coast of Malaysia and Southern Thailand, a formulated boundary condition and a moving boundary condition are simultaneously used. In this study, a boundary fitted curvilinear grid system is used in order to incorporate the coastal and island boundaries accurately as the boundaries of the model domain are curvilinear in nature and the bending is high. The tsunami response of the event 26 December 2004 along the west open boundary of the model domain is computed to simulate the effect of far field tsunami. Based on the data of the tsunami source at the west open boundary of the model domain, a boundary condition is formulated and applied to simulate the tsunami response along the coastal and island boundaries. During the simulation process, a moving boundary condition is initiated instead of fixed vertical seaside wall. The extent of inland inundation and tsunami propagation pattern are computed. Some comparisons are carried out to test the validation of the simultaneous use of the two boundary conditions. All simulations show excellent agreement with the data of observation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=open%20boundary%20condition" title="open boundary condition">open boundary condition</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20boundary%20condition" title=" moving boundary condition"> moving boundary condition</a>, <a href="https://publications.waset.org/abstracts/search?q=boundary-fitted%20curvilinear%20grids" title=" boundary-fitted curvilinear grids"> boundary-fitted curvilinear grids</a>, <a href="https://publications.waset.org/abstracts/search?q=far-field%20tsunami" title=" far-field tsunami"> far-field tsunami</a>, <a href="https://publications.waset.org/abstracts/search?q=shallow%20water%20equations" title=" shallow water equations"> shallow water equations</a>, <a href="https://publications.waset.org/abstracts/search?q=tsunami%20source" title=" tsunami source"> tsunami source</a>, <a href="https://publications.waset.org/abstracts/search?q=Indonesian%20tsunami%20of%202004" title=" Indonesian tsunami of 2004"> Indonesian tsunami of 2004</a> </p> <a href="https://publications.waset.org/abstracts/38523/combined-effect-of-moving-and-open-boundary-conditions-in-the-simulation-of-inland-inundation-due-to-far-field-tsunami" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38523.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">446</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> DNA Double-Strand Break–Capturing Nuclear Envelope Tubules Drive DNA Repair</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mitra%20Shokrollahi">Mitra Shokrollahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mia%20Stanic"> Mia Stanic</a>, <a href="https://publications.waset.org/abstracts/search?q=Anisha%20Hundal"> Anisha Hundal</a>, <a href="https://publications.waset.org/abstracts/search?q=Janet%20N.%20Y.%20Chan"> Janet N.

It is unclear to what extent human DSBs display such repositioning. Here we show that the human nuclear envelope localizes to DSBs in a manner depending on DNA damage response (DDR) kinases and cytoplasmic microtubules acetylated by α-tubulin acetyltransferase-1 (ATAT1). These factors collaborate with the linker of nucleoskeleton and cytoskeleton complex (LINC), nuclear pore complex (NPC) protein NUP153, the nuclear lamina and kinesins KIF5B and KIF13B to generate DSB-capturing nuclear envelope tubules (dsbNETs). dsbNETs are partly supported by nuclear actin filaments and the circadian factor PER1 and reversed by kinesin KIFC3. Although dsbNETs promote repair and survival, they are also co-opted during poly (ADP-ribose) polymerase (PARP) inhibition to restrain BRCA1-deficient breast cancer cells and are hyper-induced in cells expressing the aging-linked lamin A mutant progerin. In summary, our results advance understanding of nuclear structure-function relationships, uncover a nuclear-cytoplasmic DDR and identify dsbNETs as critical factors in genome organization and stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20damage%20response" title="DNA damage response">DNA damage response</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%20stability" title=" genome stability"> genome stability</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20envelope" title=" nuclear envelope"> nuclear envelope</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=age-related%20disorders" title=" age-related disorders"> age-related disorders</a> </p> <a href="https://publications.waset.org/abstracts/193774/dna-double-strand-break-capturing-nuclear-envelope-tubules-drive-dna-repair" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193774.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">16</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Predictors and 3-Year Outcomes of Compromised Left Circumflex Coronary Artery After Left Main Crossover Stenting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hameed%20Ullah">Hameed Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Elakabawi"> Karim Elakabawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20KE"> Han KE</a>, <a href="https://publications.waset.org/abstracts/search?q=Najeeb%20Ullah"> Najeeb Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Habib%20Ullah"> Habib Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Sardar%20Ali%20Shah"> Sardar Ali Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamad%20Haider%20Khan"> Hamad Haider Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Asad%20Khan"> Muhammad Asad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ning%20Guo"> Ning Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuyi%20Yuan"> Zuyi Yuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Predictors of decreased fractional flow reserve at left circumflex coronary artery after left main (LM) crossover stenting are still lacking. The objectives of the present study were to provide the predictors for low Fractional flow reserve (FFR) at coronary artery (LCx) and the possible treatment strategies for the compromised LCx-together with their long term outcomes. Methods: A total of 563 included patients out of 1974 patients admitted to our hospital from February 2015 to November 2020 with significant distal LM-bifurcation lesions. The enrolled patients underwent single-stent cross-over PCI under IVUS guidance with further LCx intervention as indicated by measured FFR. Results: The included patients showed angiographic significant LCx ostial affection after LM-stenting, but only 116 (20.6%) patients had FFR <0.8. The 3-year composite MACE rates were comparable between the high and low FFR groups (16.8% vs. 15.5%, respectively; P=0.744). In a multivariable analysis, a low FFR in the LCx was associated with post-stenting MLA of the LCx (OR: 0.032, P <0.001), post-stenting LCx-plaque burden (OR: 1.166, P <0.001), post-stenting LM-MLA (OR: 0.821, P =0.038) and pre-stenting LCx-MLA (OR: 0.371, P =0.044). In patients with low FFR, management of compromised LCx with DEB had the lowest 3-year MACE rate (8.1%) as compared to either KBI (17.5%) or stenting group (20.5%), P =0.299. Conclusion: FFR-guided LCx intervention can avoid unnecessary LCx intervention. The post-stenting predictors of low FFR include post-stenting MLA and plaque burden of the LCx and MV stent length. The 3-year MACE rates were comparable between high FFR patients and patients who had low FFR and were adequately managed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractional%20flow%20reserve" title="fractional flow reserve">fractional flow reserve</a>, <a href="https://publications.waset.org/abstracts/search?q=left%20main%20stem" title=" left main stem"> left main stem</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20coronary%20interventions" title=" percutaneous coronary interventions"> percutaneous coronary interventions</a>, <a href="https://publications.waset.org/abstracts/search?q=intravascular%20ultrasound" title=" intravascular ultrasound"> intravascular ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/185752/predictors-and-3-year-outcomes-of-compromised-left-circumflex-coronary-artery-after-left-main-crossover-stenting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185752.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">39</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> A Review of Accuracy Optical Surface Imaging Systems for Setup Verification During Breast Radiotherapy Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Auwal%20Abubakar">Auwal Abubakar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ahidjo"> Ahmed Ahidjo</a>, <a href="https://publications.waset.org/abstracts/search?q=Shazril%20Imran%20Shaukat"> Shazril Imran Shaukat</a>, <a href="https://publications.waset.org/abstracts/search?q=Noor%20Khairiah%20A.%20Karim"> Noor Khairiah A.

This study reviews the accuracy of the available commercial OSISs for breast radiotherapy. Method: A literature search was conducted and identified the available commercial OSISs from different manufacturers that are integrated into radiotherapy practice for setup verification during breast radiotherapy. Studies that evaluated the accuracy of the OSISs during breast radiotherapy using cone beam computed tomography (CBCT) as a reference were retrieved and analyzed. The physics and working principles of the systems from each manufacturer were discussed together with their respective strength and limitations. Results: A total of five (5) different commercially available OSISs from four (4) manufacturers were identified, each with a different working principle. Six (6) studies were found to evaluate the accuracy of the systems during breast radiotherapy in conjunction with CBCT as a goal standard. The studies revealed that the accuracy of the system in terms of mean difference ranges from 0.1 to 2.1 mm. The correlation between CBCT and OSIS ranges between 0.4 and 0.9. The limit of agreements obtained using bland Altman analysis in the studies was also within an acceptable range. Conclusion: The OSISs have an acceptable level of accuracy and could be used safely during breast radiotherapy. The systems are non-invasive, ionizing radiation-free, and provide real-time imaging of the target surface at no extra concomitant imaging dose. However, the system should only be used to complement rather than replace x-ray-based image guidance techniques such as CBCT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optical%20surface%20imaging%20system" title="optical surface imaging system">optical surface imaging system</a>, <a href="https://publications.waset.org/abstracts/search?q=Cone%20beam%20computed%20tomography%20%28CBCT%29" title=" Cone beam computed tomography (CBCT)"> Cone beam computed tomography (CBCT)</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20guided%20radiotherapy" title=" surface guided radiotherapy"> surface guided radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=Breast%20radiotherapy" title=" Breast radiotherapy"> Breast radiotherapy</a> </p> <a href="https://publications.waset.org/abstracts/182909/a-review-of-accuracy-optical-surface-imaging-systems-for-setup-verification-during-breast-radiotherapy-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182909.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">66</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> In Vitro Evaluation of the Antimitotic and Genotoxic Effect by the Allium cepa L.

These molecules include alkaloids, polyphenols and terpenes. The latter can be extracted by different solvents, namely: water, ethanol, methanol, butanol, acetone... This is why it seemed interesting to us to evaluate in vitro the antimitotic and genotoxic effect of these secondary metabolites contained in the aqueous extract of the leaves of Peganum harmala L. by the Allium cepa L. test on meristematic cells by calculating the mitotic parameters (The mitotic index, the aberration index and the limit value of cytotoxicity).A spectrophotometric determination of secondary metabolites, namely alkaloids and flavonoids in the aqueous extract of this essence, was performed. As a result, the alkaloid content is estimated to be 28.42 μg EC/mg extract, and the flavonoid content is 12.52 μg EQ/mg extract. The determination of the mitotic index revealed disturbances in cell division with a highly significant difference between the negative control (distilled water) and the different samples (aqueous extracts, colchicine and quecetin). The exposure of meristematic cells to our samples resulted in a large number of chromosomal, nuclear and cellular aberrations with an aberration index reaching 16.21±1.28% for the 4mg/ml aqueous extract and 11.71±3.32% for the 10mg/ml aqueous extract. The limit value of cytotoxicity revealed that our samples are sublethal on Allium cepa L. meristematic cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allium%20cepa%20l." title="allium cepa l.">allium cepa l.</a>, <a href="https://publications.waset.org/abstracts/search?q=antimitotic%20and%20genotoxic%20effect" title=" antimitotic and genotoxic effect"> antimitotic and genotoxic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20leaf%20extract" title=" aqueous leaf extract"> aqueous leaf extract</a>, <a href="https://publications.waset.org/abstracts/search?q=laghouat%20%28algeria%29" title=" laghouat (algeria)"> laghouat (algeria)</a>, <a href="https://publications.waset.org/abstracts/search?q=peganum%20harmala%20l." title=" peganum harmala l."> peganum harmala l.</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20metabolites" title=" secondary metabolites"> secondary metabolites</a> </p> <a href="https://publications.waset.org/abstracts/167156/in-vitro-evaluation-of-the-antimitotic-and-genotoxic-effect-by-the-allium-cepa-l-test-of-the-aqueous-extract-of-peganum-harmala-l-leaves-laghouat-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167156.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Integration of an Augmented Reality System for the Visualization of the HRMAS NMR Analysis of Brain Biopsy Specimens Using the Brainlab Cranial Navigation System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelkrim%20Belhaoua">Abdelkrim Belhaoua</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Pierre%20Radoux"> Jean-Pierre Radoux</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Kuras"> Mariana Kuras</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincent%20R%C3%A9camier"> Vincent Récamier</a>, <a href="https://publications.waset.org/abstracts/search?q=Martial%20Piotto"> Martial Piotto</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Elbayed"> Karim Elbayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Fran%C3%A7ois%20Proust"> François Proust</a>, <a href="https://publications.waset.org/abstracts/search?q=Izzie%20Namer"> Izzie Namer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes an augmented reality system dedicated to neurosurgery in order to assist the surgeon during an operation. This work is part of the ExtempoRMN project (Funded by Bpifrance) which aims at analyzing during a surgical operation the metabolic content of tumoral brain biopsy specimens by HRMAS NMR. Patients affected with a brain tumor (gliomas) frequently need to undergo an operation in order to remove the tumoral mass. During the operation, the neurosurgeon removes biopsy specimens using image-guided surgery. The biopsy specimens removed are then sent for HRMAS NMR analysis in order to obtain a better diagnosis and prognosis. Image-guided refers to the use of MRI images and a computer to precisely locate and target a lesion (abnormal tissue) within the brain. This is performed using preoperative MRI images and the BrainLab neuro-navigation system. With the patient MRI images loaded on the Brainlab Cranial neuro-navigation system in the operating theater, surgeons can better identify their approach before making an incision. The Brainlab neuro-navigation tool tracks in real time the position of the instruments and displays their position on the patient MRI data. The results of the biopsy analysis by 1H HRMAS NMR are then sent back to the operating theater and superimposed on the 3D localization system directly on the MRI images. The method we have developed to communicate between the HRMAS NMR analysis software and Brainlab makes use of a combination of C++, VTK and the Insight Toolkit using OpenIGTLink protocol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neuro-navigation" title="neuro-navigation">neuro-navigation</a>, <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality" title=" augmented reality"> augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=biopsy" title=" biopsy"> biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=BrainLab" title=" BrainLab"> BrainLab</a>, <a href="https://publications.waset.org/abstracts/search?q=HR-MAS%20NMR" title=" HR-MAS NMR"> HR-MAS NMR</a> </p> <a href="https://publications.waset.org/abstracts/57089/integration-of-an-augmented-reality-system-for-the-visualization-of-the-hrmas-nmr-analysis-of-brain-biopsy-specimens-using-the-brainlab-cranial-navigation-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57089.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Study of the Composition of Lipids in Different Kinds of Packaged Food Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Taidirt">Zineb Taidirt</a>, <a href="https://publications.waset.org/abstracts/search?q=Fathia%20Sebahi"> Fathia Sebahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Karim%20Guarchani"> Mohamed Karim Guarchani</a>, <a href="https://publications.waset.org/abstracts/search?q=Anissa%20Berkane"> Anissa Berkane</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Smail"> Noureddine Smail</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouahiba%20Hadjoudj"> Ouahiba Hadjoudj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cardiovascular diseases are one of the most important causes of death in Algeria. Several risk factors are responsible for this, including the consumption of foods containing saturated fat and trans fatty acids TFAs. This brief presents the results of a descriptive study of the lipid composition of 251 food products marketed in Algeria. The objective of the study is to describe the nature and composition of lipids and to verify the compliance of saturated and trans fatty acids intakes with the regulations. The study is based on data from the nutrition labelling of marketed food products. The results showed that the lipids in foodstuffs are diverse in nature and of varying amounts, but their nature is not specified on all products. In addition, the required content of saturated fatty acids is mentioned only in 29.48% of the products; 21.62% of them do not comply with the standard. Hydrogenation of fats, which produced Trans fatty acids, is common: 19.92% of products contain hydrogenated fats, and 74.89% may contain them according to the aspect of the lipid (solid fat). However, the trans fatty acid content is only mentioned in 5.18% of the products. The latter is above the limits set by Algerian regulations in 50% of the butter samples studied. The composition of lipids in mono- and polyunsaturated fatty acids essential for the body is insufficient: only 13.94% of the products inform their contents on their labels. It is necessary to adopt mandatory restriction of trans fatty acids, to ban the use of partially-hydrogenated oils, and to require required mandatory labeling of the TFAs and the other fatty acids on packaged foods, and to conduct more studies in order to appreciate the intake of TFAs and saturated fat and appreciate their effects on the Algerian population and to get more informed about the composition of the lipid in packaged foods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20diseases" title="cardiovascular diseases">cardiovascular diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=lipids" title=" lipids"> lipids</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition%20labelling" title=" nutrition labelling"> nutrition labelling</a>, <a href="https://publications.waset.org/abstracts/search?q=lipids" title=" lipids"> lipids</a>, <a href="https://publications.waset.org/abstracts/search?q=trans%20fatty%20acids" title=" trans fatty acids"> trans fatty acids</a> </p> <a href="https://publications.waset.org/abstracts/130716/study-of-the-composition-of-lipids-in-different-kinds-of-packaged-food-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130716.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Simulation and Synoptic Investigation of a Severe Dust Storm in Urmia Lake in the Middle East</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasim%20Hossein%20Hamzeh">Nasim Hossein Hamzeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Shukurov"> Karim Shukurov</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Ranjbar%20Saadat%20Abadi"> Abbas Ranjbar Saadat Abadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Mhawish"> Alaa Mhawish</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Opp"> Christian Opp</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Deserts are the main dust sources in the world.

In this study, the Urmia Lake was the source of dustfromApril 24 to April 25, 2017.The local dust storm was combined with another large-scale dust storm that originated from Saudi Arabia and Iraq 1-2 days earlier. Synoptic investigation revealed that the severe dust storm was made by a strong Black Sea cyclone and a low-pressure system over the Middle East and Central Iraq in conjunction a high-pressure system and associated with a high gradient contour and a quasi-stationary long-wave trough over the east and south of the Mediterranean Sea. Based on HYSPLIT 72 hours backward and forward trajectories, the most probable dust transport routes to and from the Urmia Lake region are estimated. Using the concentration weighted trajectory (CWT) method based on 24 hours backward and 24 hours forward trajectories, the spatial distributions of potential sources of PM10 observed in the Urmia Lake region on April 23-26, 2017. Also, the vertical profile of dust particles using the WRF-Chem model with two dust schemes showed dust ascending up to 5 km from the lake. Also, the dust schemes outputs shows that the PM10 fluctuating changes are 12 hours earlier than the measured surface PM10 at five air pollution monitoring stations around the Urmia Lake in 23-26 April 2017. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dust%20storm" title="dust storm">dust storm</a>, <a href="https://publications.waset.org/abstracts/search?q=synoptic%20investigation" title=" synoptic investigation"> synoptic investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=WRF-chem%20model" title=" WRF-chem model"> WRF-chem model</a>, <a href="https://publications.waset.org/abstracts/search?q=urmia%20lake" title=" urmia lake"> urmia lake</a>, <a href="https://publications.waset.org/abstracts/search?q=lagrangian%20trajectory" title=" lagrangian trajectory"> lagrangian trajectory</a> </p> <a href="https://publications.waset.org/abstracts/154710/simulation-and-synoptic-investigation-of-a-severe-dust-storm-in-urmia-lake-in-the-middle-east" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154710.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">214</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> A Preliminary Investigation on Factors that Influence Road Users Speeding Behaviors in Selected Roads of Peninsular Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farah%20Fazlinda%20Binti%20Mohamad">Farah Fazlinda Binti Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Hikmah%20Binti%20Musthar"> Siti Hikmah Binti Musthar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Saifizul%20Bin%20Abdullah"> Ahmad Saifizul Bin Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamilah%20Mohamad"> Jamilah Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Rehan%20Karim"> Mohamed Rehan Karim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Road safety is intolerable issue. It affects and impinges on everyone's life as the roads shared by everyone. The most vulnerable victims were the road users who cater the roads every day. It is an appalling when World Health Organization reported that Malaysian road users were ranked worst in Asian countries with 23 deaths for every 100,000 of population over the span of 12 years (World Health Organization, 2009). From this report, it is found that speeding has contributed to 60% of all accidents in the country. Therefore, this study aims to elucidate on speeding matter that occur among road users in selected roads of Peninsular Malaysia. This study on the other hand, provides an insight understanding on the factors affecting behaviour of road users to speeding in selected roads of Peninsular Malaysia. To answer the study aims, 500 sets of questionnaires were distributed among 500 respondents in selected roads of Peninsular Malaysia to obtain their opinions on the matter. The respondents were from different demographics backgrounds to have fair explanation on the issue. The answers have been analysed using descriptive analysis. The results indicated psychological factors of road users appeared to be prominent in explaining road users’ behaviour to speeding. Male road users were also found dominant in speeding compared to female. Thus, this has increased their vulnerability to road injuries and deaths. These findings are very useful in order for us to improve our driving behaviour. Relevant authorities should also revise the existing countermeasures as well as designing the new countermeasures for the road users. It is nevertheless important to comprehend this speeding issue and factors associating it.

It is a minimally invasive procedure using biochemical properties of ozone resulting in reduced volume of disc and inflammation resulting in significant pain relief. Aim: The purpose of this study was to evaluate the effectiveness of ozone therapy in combination with peri-ganglionic injection of local anesthetic and corticosteroid. Material and Methods: This retrospective study was done at the Interventional Radiology Department of Mayo Hospital, Lahore. A total of 49000 patients were included from January 2008 to March 2022. All the patients presented with clinical signs and symptoms of lumber disc herniation, which was confirmed by a MRI scan of the lumbar sacral spine. The pain reduction was calculated using modified MacNab method. All the patients underwent percutaneous injection of ozone at a concentration of 27 micrograms/ml to lumber disc under fluoroscopic guidance with combination of local anesthetic and corticosteroid in peri-ganglionic space. Results were evaluated by two expert observers who were blinded to patient treatment. Results A satisfactory therapeutic outcome was obtained. 55% of the patients showed complete recovery with resolution of symptoms. 20% of the patients complained of occasional episodic pain with no limitation of occupational activity. 15% of cases showed insufficient improvement. 5% of cases had insufficient improvement and went for surgery. 10% of cases never turned up after the first visit. Conclusion Intradiscal ozone for the treatment of herniated discs has revolutionized percutaneous approach to nerve root compression making it safer, economical and easier to repeat without any side effects than treatments currently used in Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pain" title="pain">pain</a>, <a href="https://publications.waset.org/abstracts/search?q=prolapse" title=" prolapse"> prolapse</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozone" title=" Ozone"> Ozone</a>, <a href="https://publications.waset.org/abstracts/search?q=backpain" title=" backpain"> backpain</a> </p> <a href="https://publications.waset.org/abstracts/188838/ozone-therapy-for-disc-herniation-a-non-surgical-option" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188838.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">27</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Analysis of a Damage-Control Target Displacement of Reinforced Concrete Bridge Pier for Seismic Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Ritzman%20Abdul%20Karim">Mohd Ritzman Abdul Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhaohui%20Huang"> Zhaohui Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A current focus in seismic engineering practice is the development of seismic design approach that focuses on the performance-based design. Performance-based design aims to design the structures to achieve specified performance based on the damage limit states. This damage limit is more restrictive limit than life safety and needs to be carefully estimated to avoid damage in piers due to failure in transverse reinforcement. In this paper, a different perspective of damage limit states has been explored by integrating two damage control material limit state, concrete and reinforcement by introduced parameters such as expected yield stress of transverse reinforcement where peak tension strain prior to bar buckling is introduced in a recent study. The different perspective of damage limit states with modified yield displacement and the modified plastic-hinge length is used in order to predict damage-control target displacement for reinforced concreate (RC) bridge pier. Three-dimensional (3D) finite element (FE) model has been developed for estimating damage target displacement to validate proposed damage limit states. The result from 3D FE analysis was validated with experimental study found in the literature. The validated model then was applied to predict the damage target displacement for RC bridge pier and to validate the proposed study. The tensile strain on reinforcement and compression on concrete were used to determine the predicted damage target displacement and compared with the proposed study. The result shows that the proposed damage limit states were efficient in predicting damage-control target displacement consistent with FE simulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage-control%20target%20displacement" title="damage-control target displacement">damage-control target displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20limit%20states" title=" damage limit states"> damage limit states</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20bridge%20pier" title=" reinforced concrete bridge pier"> reinforced concrete bridge pier</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20displacement" title=" yield displacement"> yield displacement</a> </p> <a href="https://publications.waset.org/abstracts/99016/analysis-of-a-damage-control-target-displacement-of-reinforced-concrete-bridge-pier-for-seismic-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99016.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> A Preliminary Investigation on Factors That Influence Road Users' Speeding Behaviour on Selected Roads in Peninsular Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farah%20Fazlinda%20Binti%20Mohamad">Farah Fazlinda Binti Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Saifizul%20Abdullah"> Ahmad Saifizul Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Rehan%20Karim"> Mohamed Rehan Karim </a>, <a href="https://publications.waset.org/abstracts/search?q=Jamilah%20Mohamad"> Jamilah Mohamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Hikmah%20Musthar"> Siti Hikmah Musthar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Road safety is an important issue in Malaysia. It become important as it is discussed widely throughout printed and electronic media. Most of the news portrays on road accident and fatalities have increased the concern of everyone. This issue affects everyone's life as everyone shares the roads. The most vulnerable victims are the road user who uses the roads every day. It is appalling when World Health Organization (WHO) reported that in every 100,000 of population in Malaysia, 23 fatalities recorded due to road accident alone. This figure is quite alarming and requires serious attention. Furthermore, research by Malaysian Institute of Road Safety Research concluded that that speeding has contributed to 60% of all road accident in the country. Therefore, this study aims to elucidate the factors that influence road users’ speeding behaviour on selected roads in Peninsular Malaysia. To achieve this, set of questionnaires has distributed to 500 respondents on selected roads in Peninsular Malaysia. The respondents came from various demographic backgrounds in order to have a fair opinion on the issue. Using descriptive analysis, the results have indicated that psychological factors such as emotion and attitude of road user are the prominent factors that influence the road user’s speeding behaviour. Furthermore, the results have shown that male road users were dominant in speeding compared to female, which led to increased vulnerability to road injuries and fatalities. These findings are very useful in order for us to understand road users’ driving behaviour. Relevant authorities should also revise the existing countermeasures and find ways to reduce road accident. Engineers and road experts could cooperate in designing new road specifications for the road user. Nevertheless, it is important to comprehend this speeding issue and factors associated with it. Each road user should take this matter seriously and responsibly as road safety is a responsibility of all. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=countermeasures" title="countermeasures">countermeasures</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological" title=" psychological"> psychological</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety"> road safety</a>, <a href="https://publications.waset.org/abstracts/search?q=speeding" title=" speeding"> speeding</a> </p> <a href="https://publications.waset.org/abstracts/35364/a-preliminary-investigation-on-factors-that-influence-road-users-speeding-behaviour-on-selected-roads-in-peninsular-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35364.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">527</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Molecularly Imprinted Nanoparticles (MIP NPs) as Non-Animal Antibodies Substitutes for Detection of Viruses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Poma">Alessandro Poma</a>, <a href="https://publications.waset.org/abstracts/search?q=Kal%20Karim"> Kal Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergey%20Piletsky"> Sergey Piletsky</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppe%20Battaglia"> Giuseppe Battaglia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recent increasing emergency threat to public health of infectious influenza diseases has prompted interest in the detection of avian influenza virus (AIV) H5N1 in humans as well as animals. A variety of technologies for diagnosing AIV infection have been developed. However, various disadvantages (costs, lengthy analyses, and need for high-containment facilities) make these methods less than ideal in their practical application. Molecularly Imprinted Polymeric Nanoparticles (MIP NPs) are suitable to overcome these limitations by having high affinity, selectivity, versatility, scalability and cost-effectiveness with the versatility of post-modification (labeling – fluorescent, magnetic, optical) opening the way to the potential introduction of improved diagnostic tests capable of providing rapid differential diagnosis. Here we present our first results in the production and testing of MIP NPs for the detection of AIV H5N1. Recent developments in the solid-phase synthesis of MIP NPs mean that for the first time a reliable supply of ‘soluble’ synthetic antibodies can be made available for testing as potential biological or diagnostic active molecules. The MIP NPs have the potential to detect viruses that are widely circulating in farm animals and indeed humans. Early and accurate identification of the infectious agent will expedite appropriate control measures. Thus, diagnosis at an early stage of infection of a herd or flock or individual maximizes the efficiency with which containment, prevention and possibly treatment strategies can be implemented. More importantly, substantiating the practicability’s of these novel reagents should lead to an initial reduction and eventually to a potential total replacement of animals, both large and small, to raise such specific serological materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=influenza%20virus" title="influenza virus">influenza virus</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20imprinting" title=" molecular imprinting"> molecular imprinting</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=polymers" title=" polymers"> polymers</a> </p> <a href="https://publications.waset.org/abstracts/29566/molecularly-imprinted-nanoparticles-mip-nps-as-non-animal-antibodies-substitutes-for-detection-of-viruses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29566.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">362</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Childhood Warscape, Experiences from Children of War Offer Key Design Decisions for Safer Built Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soleen%20Karim">Soleen Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Meira%20Yasin"> Meira Yasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Rezhin%20Qader"> Rezhin Qader</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Children’s books present a colorful life for kids around the world, their current environment or what they could potentially have- a home, two loving parents, a playground, and a safe school within a short walk or bus ride. These images are only pages in a donated book for children displaced by war. The environment they live in is significantly different. Displaced children are faced with a temporary life style filled with fear and uncertainty. Children of war associate various structural institutions with a trauma and cannot enter the space, even if it is for their own future development, such as a school. This paper is a collaborative effort with students of the Kennesaw State University architecture department, architectural designers and a mental health professional to address and link the design challenges and the psychological trauma for children of war. The research process consists of a) interviews with former refugees, b) interviews with current refugee children, c) personal understanding of space through one’s own childhood, d) literature review of tested design methods to address various traumas. Conclusion: In addressing the built environment for children of war, it is necessary to address mental health and well being through the creation of space that is sensitive to the needs of children. This is achieved by understanding critical design cues to evoke normalcy and safe space through program organization, color, and symbiosis of synthetic and natural environments. By involving the children suffering from trauma in the design process, aspects of the design are directly enhanced to serve the occupant. Neglecting to involve the participants creates a nonlinear design outcome and does not serve the needs of the occupant to afford them equal opportunity learning and growth experience as other children around the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activist%20architecture" title="activist architecture">activist architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=childhood%20education" title=" childhood education"> childhood education</a>, <a href="https://publications.waset.org/abstracts/search?q=childhood%20psychology" title=" childhood psychology"> childhood psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=adverse%20childhood%20experiences" title=" adverse childhood experiences"> adverse childhood experiences</a> </p> <a href="https://publications.waset.org/abstracts/96148/childhood-warscape-experiences-from-children-of-war-offer-key-design-decisions-for-safer-built-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96148.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Feasibility of Solar Distillation as Household Water Supply in Saline Zones of Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Rezaul%20Karim">Md.

In equinoctial countries like Bangladesh, where sunlight is available for more than 10 hours a day, Solar Distillation provides a promising sustainable way for safe drinking water supply in coastal poor households with negligible major cost and difficulty of construction and maintenance. In this paper, two passive type solar stills- a Conventional Single Slope Solar still (CSS) and a Pyramid Solar Sill (PSS) is used and relationship is established between distill water output corresponding to four different factors- temperature, solar intensity, relative humidity and wind speed for Gazipur, Bangladesh. Comparison is analyzed between the two different still outputs for nine months period (January- September) and efficiency is calculated. Later a thermal mathematical model is developed and the distilled water output for Khulna, Bangladesh is computed. Again, difference between the output of the two cities- Gazipur and Khulna is demonstrated and finally an economic analysis is prepared. The distillation output has a positive correlation with temperature and solar intensity, inverse relation with relative humidity and wind speed has nugatory consequence. The maximum output of Conventional Solar Still is obtained 3.8 L/m2/day and Pyramid still is 4.3 L/m2/day for Gazipur and almost 15% more efficiency is found for Pyramid still. Productivity in Khulna is found almost 20% more than Gazipur. Based on economic analysis, taking 10 BDT, per liter, the net profit, benefit cost ratio, payback period all indicates that both stills are feasible but pyramid still is more feasible than Conventional Still. Finally, for a 3-4 member family, area of 4 m2 is suggested for Conventional Still and 3m2 for Pyramid Solar Still. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20distillation" title="solar distillation">solar distillation</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20water%20supply" title=" household water supply"> household water supply</a>, <a href="https://publications.waset.org/abstracts/search?q=saline%20zones" title=" saline zones"> saline zones</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title=" Bangladesh"> Bangladesh</a> </p> <a href="https://publications.waset.org/abstracts/40325/feasibility-of-solar-distillation-as-household-water-supply-in-saline-zones-of-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40325.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">271</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Constrains to Financial Engineering for Liquidity Management: A Multiple Case Study of Islamic Banks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadia%20Bibi">Sadia Bibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Ullah"> Karim Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Islamic banks have excess liquidity, which needs proper management to earn a high rate of return on them to remain competitive. However, they lack assets-backed avenues and rely on a few sukuks, which led them to liquidity management issues. Financial engineering comes forward to innovate and develop instruments for the requisite financial problem. Still, they face many challenges, explored in the context of liquidity management in Islamic banks. The rigorous literature review shows that Shariah compliance, competition from the conventional banks, lack of sufficient instruments, derivatives are still not accepted as legitimate products, the inter-bank market being less developed, and no possibility of lender of last resort is the six significant constraints to financial engineering for liquidity management of Islamic banks. To further explore the problem, a multiple case study strategy is used to extend and develop the theory with the philosophical stance of social constructivism. Narrative in-depth interviews over the telephone are conducted with key personnel at treasury departments of selected banks. Data is segregated and displayed using NVivo 11 software, and the thematic analysis approach identifies themes related to the constraints. The exploration of further constraints to financial engineering for liquidity management of Islamic banks achieves the research aim. The theory is further developed by the addition of three more constraints to the theoretical framework, which are i) lack of skilled human resources, ii) lack of unified vision, and iii) lack of government support to the Islamic banks. These study findings are fruitful for the use of the government, regulatory authorities of the banking sector, the State Bank of Pakistan (Central Bank), and the product design & development division of Islamic banks to make the financial engineering process feasible and resolve liquidity management issues of Islamic banks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20engineering" title="financial engineering">financial engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=liquidity%20management" title=" liquidity management"> liquidity management</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20banks" title=" Islamic banks"> Islamic banks</a>, <a href="https://publications.waset.org/abstracts/search?q=shariah%20compliance" title=" shariah compliance"> shariah compliance</a> </p> <a href="https://publications.waset.org/abstracts/162889/constrains-to-financial-engineering-for-liquidity-management-a-multiple-case-study-of-islamic-banks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162889.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Mapping Social and Natural Hazards: A Survey of Potential for Managed Retreat in the United States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Ahmed">Karim Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to investigate how factoring the impact of natural disasters beyond flooding would affect managed retreat policy eligibility in the United States. For the study design, a correlation analysis method compared weighted measures of flooding and other natural disasters (e.g., wildfires, tornadoes, heatwaves, etc.) to CBSA Populated areas, the prevalence of cropland, and relative poverty on a county level. The study found that the vast majority of CBSAs eligible for managed retreat programs under a policy inclusive of non-flooding events would have already been covered by flood-only managed retreat policies. However, it is noteworthy that a majority of those counties that are not covered by a flood-only managed retreat policy have high rates of poverty and are either heavily populated and/or agriculturally active. The correlation is particularly strong between counties that are subject to multiple natural hazards and those that have both high rates of relative poverty and cropland prevalence. There is currently no managed retreat policy for agricultural land in the United States despite the environmental implications and food supply chain vulnerabilities related to at-risk cropland. The findings of this study suggest both that such a policy should be created and, when it is, that special attention should be paid to non-flood natural disasters affecting agricultural areas. These findings also reveal that, while current flood-based policies in the United States serve many areas that do need access to managed retreat funding and implementation, other vulnerable areas are overlooked by this approach. These areas are often deeply impoverished and are therefore particularly vulnerable to natural disaster; if and when those disasters do occur, these areas are often less financially prepared to recover or retreat from the disaster’s advance and, due to the limitations of the current policies discussed above, are less able to take the precautionary measures necessary to mitigate their risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flood" title="flood">flood</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard" title=" hazard"> hazard</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use" title=" land use"> land use</a>, <a href="https://publications.waset.org/abstracts/search?q=managed%20retreat" title=" managed retreat"> managed retreat</a>, <a href="https://publications.waset.org/abstracts/search?q=wildfire" title=" wildfire"> wildfire</a> </p> <a href="https://publications.waset.org/abstracts/130248/mapping-social-and-natural-hazards-a-survey-of-potential-for-managed-retreat-in-the-united-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130248.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Comparative Evaluation of a Dynamic Navigation System Versus a Three-Dimensional Microscope in Retrieving Separated Endodontic Files: An in Vitro Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20H.%20Karim">Mohammed H.

Materials and Methods: Thirty maxillary first bicuspids with sixty separate roots were split into two comparable groups based on a comprehensive Cone-Beam Computed Tomography (CBCT) analysis of the root length and curvature. After standardized access opening, glide paths, and patency attainment with the K file (sizes 10 and 15), the teeth were arranged on 3D models (three per quadrant, six per model). Subsequently, controlled-memory heat-treated NiTi rotary files (#25/0.04) were notched 4 mm from the tips and fractured at the apical third of the roots. The C-FR1 Endo file removal system was employed under both guidance to retrieve the fragments, and the success rate, canal aberration, treatment time and volumetric changes were measured. The statistical analysis was performed using IBM SPSS software at a significance level of 0.05. Results: The microscope-guided group had a higher success rate than the DNS guidance, but the difference was insignificant (p > 0.05). In addition, the microscope-guided drills resulted in a substantially lower proportion of canal aberration, required less time to retrieve the fragments and caused minimal change in the root canal volume (p < 0.05). Conclusion: Although dynamically guided trephining with the extractor can retrieve separated instruments, it is inferior to three-dimensional microscope guidance regarding treatment time, procedural errors, and volume change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=separated%20instruments%20retrieval" title="separated instruments retrieval">separated instruments retrieval</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20navigation%20system" title=" dynamic navigation system"> dynamic navigation system</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20video%20microscope" title=" 3D video microscope"> 3D video microscope</a>, <a href="https://publications.waset.org/abstracts/search?q=trephine%20burs" title=" trephine burs"> trephine burs</a>, <a href="https://publications.waset.org/abstracts/search?q=extractor" title=" extractor"> extractor</a> </p> <a href="https://publications.waset.org/abstracts/169053/comparative-evaluation-of-a-dynamic-navigation-system-versus-a-three-dimensional-microscope-in-retrieving-separated-endodontic-files-an-in-vitro-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169053.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">69</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Assessing Water Bottle Consumption on College Campus in Abu Dhabi: Towards a Sustainable Future</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ludmilla%20Wikkeling-Scott">Ludmilla Wikkeling-Scott</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Karim"> Amira Karim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In a rapidly developing environment, concerns for pollution and depletion of natural resources are challenges facing global communities. A major source of waste on university campuses is the use of plastic bottles, while cost of production and processing is high. Consumer demand stimulates popularity of plastic bottle production, but researchers agree this is not a sustainable solution. This pilot study assesses plastic water bottle used and attitude towards alternatives among Emirati college students. Methods: This study was conducted in December 2016, using an anonymous self-administered survey of 17 questions. The survey included personal characteristics, plastic water bottle used, attitude towards alternative replacement and sustainability. For statistical analysis, STATA 14C was used to determine significance of association. Results: A total of 500 Emirati students (94.6% female) completed the survey. Of the students, 82.6% preferred bottled water over tap water, and 44.6% reported disposable bottled water use in their household, 42.6% purchased disposable bottled water more than twice a week, and 44.2% purchased bottled water at least once, while on campus. Students were willing to consider switching to alternative water bottle use if it was more convenient (22.54%), cost less (55.13%) or improved the taste (22.54%), while only 7.85% students would not consider any alternatives. There was a significant difference in attitude towards alternatives to water bottle use by area of study (p < 0.005). Conclusion: The UAE strives to be at the forefront of sustainable development and protecting biodiversity. However, a major challenge is the increasing amount of waste, exacerbated by the increasing consumer demand for convenience as seen in this billion-dollar industry. Plastic bottles, for all purposes, pose a serious threat to the environment and sustainable campus initiatives can help reduce the ecological footprint, improve awareness of safe alternatives and benefits to the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecological%20foot%20print" title="ecological foot print">ecological foot print</a>, <a href="https://publications.waset.org/abstracts/search?q=emirati%20students" title=" emirati students"> emirati students</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20bottle%20consumption" title=" plastic bottle consumption"> plastic bottle consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20campus" title=" sustainable campus"> sustainable campus</a> </p> <a href="https://publications.waset.org/abstracts/72272/assessing-water-bottle-consumption-on-college-campus-in-abu-dhabi-towards-a-sustainable-future" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72272.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> The Investigation of Oil Price Shocks by Using a Dynamic Stochastic General Equilibrium: The Case of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bahram%20Fathi">Bahram Fathi</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Alizadeh"> Karim Alizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Mohammadbagheri"> Azam Mohammadbagheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper is to investigate the role of oil price shocks in explaining business cycles in Iran using a dynamic stochastic general equilibrium approach. This model incorporates both productivity and oil revenue shocks. The results indicate that productivity shocks are relatively more important to business cycles than oil shocks. The model with two shocks produces different values for volatility, but these values have the same ranking as that of the actual data for most variables. In addition, the actual data are close to the ratio of standard deviations to the output obtained from the model with two shocks. The results indicate that productivity shocks are relatively more important to business cycles than the oil shocks. The model with only a productivity shock produces the most similar figures in term of volatility magnitude to that of the actual data. Next, we use the Impulse Response Functions (IRF) to evaluate the capability of the model. The IRF shows no effect of an oil shock on the capital stocks and on labor hours, which is a feature of the model. When the log-linearized system of equations is solved numerically, investment and labor hours were not found to be functions of the oil shock. This research recommends using different techniques to compare the model’s robustness. One method by which to do this is to have all decision variables as a function of the oil shock by inducing the stationary to the model differently. Another method is to impose a bond adjustment cost. This study intends to fill that gap. To achieve this objective, we derive a DSGE model that allows for the world oil price and productivity shocks. Second, we calibrate the model to the Iran economy. Next, we compare the moments from the theoretical model with both single and multiple shocks with that obtained from the actual data to see the extent to which business cycles in Iran can be explained by total oil revenue shock. Then, we use an impulse response function to evaluate the role of world oil price shocks. Finally, I present implications of the findings and interpretations in accordance with economic theory. <p class="card-text"><strong>Keywords:</strong> <a
